    All of my ARís equipped with magnified optics also have two-stage triggers and all will throw the first round high if a chamber using the charging handle. If I load by releasing the BCG from lock-back, the first round is not thrown and the groups are even.

    I believe that releasing the bolt more closely mimics the cycling of the action after a fired round.

    Agree with the load function. In Highpower, the rounds from a mag will shoot differently than those singly loaded of a mag with a sled follower. .

    The 'Cold shooter' is easily tested if you have two guns (hopefully the same) and have the shooter shoot that first and then go straight to the other cool gun. You could even pick and replace the gun for each shot to make it perfectly the same.

    Sound like you are not dealing with a clean and cold bore, but rather a dirty and 'cool' bore shot. The gun might not be 'hot' but is has been shot that day and not cleaned?

    I'd try the bolt release load and see what happens.

    Not dealing with a clean bore. Once I break a rifle in, I typically only clean when the groups starting noticeably exceeding the baseline of the given rifle. For example, if the rifle averages 1 MOA at 100 yards, I'll shoot groups again when I start missing easy 1.5 MOA targets.

    I've been releasing from bolt release since I built the rifle. I'm going to re-evaluate at 500 rounds and see if the tendency to have a flyer is diminished.

    Never considered this a possibility. I'll have to try it next time I'm at the range.

    Cold bore like stated is a cold shooter.
